摘　　要：对连续可变凸轮相位器系统进行了分析,建立了系统的数学模型,并利用MATLAB/SIMUINK软件进行了仿真研究,分析了相位器工作参数和相位器结构参数对相位器的响应速度的影响。计算表明,油温、油压、相位器的叶片有效面积、叶片力臂、弹簧预加载荷、弹簧强度对相位器的响应速度有显著的影响,而相位器的转动惯量相对于整个可变配气相位系统的影响不明显。通过研究相位器系统的工作原理,揭示了系统各种工作参数对其工作响应的影响规律,为相位器系统的设计制造提供可靠的参数和依据。Through analysis of the hydraulic system, a continuously variable cam phaser （CVCP） mathematical model was set up, The influences of different working parameters and structure parameters of CVCP were discussed by using the MATLAB/SIMULINK code with strong capability of engineering calculation and the number analysis. The results demonstrate that travel speed is much sensitive to the oil temperature, oil pressure, vane area, arm of force, spring pre load torque and spring stiffness of CVCP and that the moment of inertia of CVCP has little influence on the travel speed, According to the study of the system＇s operational mechanism, the effect of various parameters of CVCP on its operation process was revealed, It can provide reliable parameter and data to the mechanical design.
